WRENCH.

Specification of Letters Patent.

Patented May 30, 1916.

Application filed February 15, 1916. Serial No. 78,442.

To all whom it may concern Be it known that I, FRANK J. BAsso, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain newand useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of this invention is to provide a novel type of wrench, that can be quickly adjusted to accommodate the different sizes of nuts and which is provided with a pair of auxiliary jaws, which may have sharpened edges, one of which auxiliary jaws is movable and adapted to be moved in the direction of the other auxiliary jaw, during the adjustment of the main jaws of the wrench.

Another object of the invention is to so mount the auxiliary jaws that they may be relieved of considerable strain, when in operative position, and also to admit of their immediate removal when it is desired to substitute new ones.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming a part thereof, in which: A

Figure 1 is a side view of the wrench showing the main jaws and the auxiliary jaws in opened position, Fig. 2 is bottom plan View of the wrench shown in Fig. 1, Fig. 3 is a side view of the wrench showing the main and auxiliary jaws in operative position, Fig. 4 is a view showing the other side of the wrench shown in Fig. 3, Fig. 5 is a detail sectional view taken on the line 55 of Fig. 1, Fig. 6 is horizontal detail sectional view taken on the line 66 of Fig. 2, Fig. 7 is a perspective view of the connecting ends of the handle of the wrench, Fig. 8 is a detail longitudinal sectional view, taken through the shank of the stationary jaw of the wrench.

Referring to the drawings more in detail, the numeral 1 designates a handle, having its opposite sides provided, adjacent its inner end, with beveled faces 2, and the said inner end of the handle is bifurcated, to provide the fingers 3 and 4. Associated with the handle 1, is a stationary jaw designated 5, which is provided with an elongated shank 6, the lower free end of which is received between the fingers 3 and 4 and is provided wlth a transverse opening which registers with similar transverse openings in the fingers 3 and 4 for the reception of a pivot pin 8. The sides of the shank 6, are provided at points below the jaw 5 with recesses, in which recesses are mounted plates 9 and 10, the said plates being held within the recesses by means of fastening elements 11 which extend through the plates 9 and 10 and through the shank 6. The plates 9 and 10 have fPOItiOIlS which project beyond the inner side of the jaw and shank 5 and 6, and a plate 12 is interposed between the proj ected portions-of the plates 9 and 10 and see cured thereto in any suitable manner. The plate 9 has its upper edge terminating short of the upper edge of the plate 10 and provides a seat for a jaw 13, which has a shank 13 extending throughout the length of the 1 plate 9, and the said jaw is held in place by means of the fastening element 15 which extends through the shank of the jaw 13 and through the shank 6 which carries the with a cutting edge 16.

Cooperating with the stationary jaw 5 is V a movable jaw 18 carried by an elongated shank 17 which is slidably positioned between the extended portions of the plates 9 and 10, and has its lower end positioned between the upper end of arcuately shaped links 19 and 20, and pivoted thereto by means of the pivot pin 21. The lower ends of the links 19 and 20 lie on the opposite sides of the handle 1 against the faces 2, and are secured thereto by means of a transversely extending pivot pin 22.

The shank 17 has that side adjacent the plate 9 provided with a recess 23 located at the upper end of the shank 17 and receives a flanged portion 24 which is carried by the jaw 25, which jaw is arranged in alinement with the jaw 13 and preferably provided with a beveled cutting edge 26, and the said jaw 25 is adapted to be held in position by a transversely extending bolt 27 which extends through the flanged portion 24 and the shank 17 and has its outer end received by-a nut 28 which is adjustable against the adj acent side of the shank17.

means 15 and 27 will be relieved from strain when the jaws 16 and 25 are moved against an article placed therebetween.

Having thus described my invention, 1

claim:

A Wrench comprising a stationary jaw, a shank carried by the stationary j aw; a movable jaw, a shank carried by the movable jaw and extending in parallel relation with the shank oi the stationary jaw, a ham dle having one end pivoted to the shank of Games 01- this patent may be ohtaine dfor fivacents each,v by addressing, the Gommissienez: atria/tents.
